<p>HBase要想查询快速，只能从rowKey上下手rowKey&#x3D;phoneNum+时间 可以实现目标1，但是目标2很难实现rowKey&#x3D;时间+phoneNum 可以实现目标2，但是目标1很难实现，且数据量越来越大可能导致热点问题 。</p>
</li>
<li><p>解决思路1：牺牲空间换时间，写数据时同时写入两张表，内容一样，只是一张表rowKey&#x3D;phoneNum+时间，另一张表rowKey&#x3D;时间+phoneNum</p>
</li>
<li><p>解决思路2：牺牲部分空间部分时间，两张表，一张全量表，rowKey&#x3D;phoneNum+时间，另一张索引表只存rowKey&#x3D;时间+phoneNum，目标1通过scan全量表就可以实现，目标2先scan索引表然后批量get全量表。</p>
